Six months before he turned the world upside down by becoming the defendant in the Trial of the Century, O.J. Simpson celebrated with Donald Trump at the GOP presidential candidate”s lavish 1993 wedding to Marla Maples.

Inside Edition has uncovered old video of the former NFL great arriving at the Plaza Hotel in New York, where Trump was tying the knot with Maples, his long-time mistress who would become wife no. 2.

Six months later, the bloody bodies of Simpson”s ex-wife Nicole Brown Simpson and her friend Ronald Goldman were found outside her Brentwood, California condominium. A few days, and a massively televised Ford Bronco chase later, Simpson was arrested and charged with the murders.

America has had a chance to revisit the case with the 10-part hit FX mini-series, “The People v. O.J. Simpson,” which wound up Tuesday night with — no spoiler here — Simpson being acquitted of the killings.

In the archived footage from Inside Edition, the “Juice” arrives at the hotel, among a 1,100 other rich and famous guests. He speaks glowingly and perhaps portentously about the power of true love. He said: “I think everybody in the country believes maybe their relationship can work, if this relationship can work, you know?”

For the wedding to her real-estate mogul beau, Maples, then 29, wore a 7.5 carat Harry Winston engagement ring and Carolina Herrera dress, topped off with a borrowed $2 million tiara.

Alas, true love didn”t work out for Maples and Trump, or for Simpson either.

Maples and Trump divorced six years later and Maples moved to the West Coast where she raised their daughter Tiffany, now 22, as a single parent.

While Trump bombastically pursues the GOP nomination for president, Maples continues her bid to win the mirror ball trophy on Season 22 of “Dancing With the Stars.”

And Simpson? Even though he was acquitted of the homicides, he was essentially a social pariah, banned from his favorite golf courses and found liable in a wrongful death civil suit brought by Goldman”s family.

He”s currently serving a 33-year sentence in an unrelated robbery and kidnapping case in Nevada.
